The Leone Stars are currently scheduled to host DR Congo on 10 September.

As a result of Caf's directive, Guinea will need to find a new venue for their Group E tie against visiting Togo on 5-6 September.

Caf has also moved to allay fears centred on the countries' away fixtures, saying that "each federation whose country is affected by the virus must ensure their delegations travelling abroad can be examined before departure".

It added that "each national association receiving delegations must communicate the necessary information delivered by health authorities to ensure the reception of teams... and if necessary to provide additional checks at arrival points".

Sierra Leone are due to play Ivory Coast, DR Congo and Cameroon in the last round of qualifying, which runs from early September to mid-November.

There could be further complications after Ivory Coast, who are set to host the Leone Stars in early September, suspended all flights to and from Sierra Leone earlier this week.

Guinea's group also includes Ghana and Uganda.

The qualifying competition will decide the 15 teams to join hosts Morocco at the Nations Cup finals in January and February next year.
